If God is God He is not good, if God is good He is not God; take the even, take the odd.

. . . what humanity most desperately needs is not the creation of new worlds but the recreation in terms of human comprehension of the world we have -- and it is for this reason that arts go on for generation to generation in spite of the fact that Phidias has already carved and Homer has already sung. The creation, we are informed, was accomplished in seven days with Sunday off, but the recreation will never be accomplished because it is always accomplished anew for each generation of living men.

What happened at Hiroshima was not only that a scientific breakthrough had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.

Never in all their history have men been able truly to conceive of the world as one: a single sphere, a globe, having the qualities of a globe, a round earth in which all the directions eventually meet, in which there is no center because every point, or none, is center - an equal earth which all men occupy as equals. The airman's earth, if free men make it, will be truly round: a globe in practice, not in theory.

Our reliance in this country is on the inquiring, individual human mind. Our strength is founded there; our resilience, our ability to face an ever-changing future and to master it. We are not frozen into the backward-facing impotence of those societies, fixed in the rigidness of an official dogma, to which the future is the mirror of the past. We are free to make the future for ourselves.
